I have developed some plugin code in RSA6.0. I wanted to migrate that
plugin to RSA7.0. I have used some classes like
WebProjectInfo
WebProjectFeature
AbstractWebProjectFeature
IWebProjectWizard
IWebProjectFeatureOperation
I would like to know, what are the replacement classes in RSA7.0 for the
above classes.
Please do help me

In order for people to help you with this question. You will need to
translate RSA version numbers into WTP version numbers. Which version of
WTP was RSA 6.0 based on? What about 7.0? You also will need to provide
full package names for these classes.

I am afraid you will have to seek help with these classes internally at
IBM. If you have specific questions regarding how to use specific API in
a particular version of WTP, feel free to post them here.
